TO ALL WHOM IT, MAY CONERN:

Be it known that I,`HARLOW C. SMITH, of Champaign City, county of Champaign, and State of Illinois, have invented new and useful improvements in Sieves1 for Sifting Flour, Meal, Svc., for family use; and I do herebyr decla-re that the following is a full, clear, and exact description o'f the same, reference being had to the accompanying drawings and letters oi' reference marked thereon.'

i The nature of my invention consists in constructing a sieve in an elongated shape, open at one end, `and situated on an incline, that, in sifting, the refuse will pass out, While -in operation, unobstructed; also, in 'pro-V viding an economical dev'ice for-operating and giving motion to the`same. In the annexed drawings, making a part of this specication- V Figurel is a top view, showing the shape and connection of sieveB with wheel C.

Figure .2 gives a side sectional View, showing the hopper D and the incline of sieve B.

Figure 3, the back and end view of case A, also the laperture H for the escape of the refuse.

Figure 4c is a full front view of Wheel' C, showing the shape ofthe rim, crank, 85o.

v To enable others skilled in the art to make and use my invention, I will proceed to describe `its construction and operationn i The case A is composed of Wood, its length, width, and depth being nearly equal. The hopper D, which fills the enclosure at the top of case A, converges from thence with its four sides to a proper-sized orifice at M, .and in such angles as to deposit the substance'to be sifted at or near the top of the sieve B.- Sieve B is made of wire cloth, such as is generally used for this purpose,Y with tin or Wood sides, and one end sufficiently high to prevent the A'flour or meal from escaping over the sides while in motion, one endvbeing open, and this end attached fby pivot or screw N suiciently loose to turnon this as a centre to case A, and in the opening' H, the other end being elevated to such a degree as to facilitate the escaping ofthe refuse through the opening H when operatedn The curved wire E E, which is attached to the sides of case A at J, supports, and, with the hooks 0 attached to sieve B, retains, the upper end of sieve B on the wire E E. At the upper end of sieve B stands wheel C, which is' composed of wood, and whose rim, composed of notches or part circles, made so as to connect a concave and `convex surface alternately until these complete the rim ,of wheel C. This wheel C .revolves with the axle S, to which it is iirmly attached, and at the other end of axle S is attached a crank, GK. This axle S passes through the front side of case A. The letter I represents an iron rod rmly attached to sieve B, .and which follows in the notched-surfaced rim of wheel C, and which is retained thus by the spring F fastened to case A, and working against the side of siev'e B. The letter L represents the Abent rim which is `attached also to the front and elevated end of sieve B,- one end of which operates with the motion of v siev-e B through the aperture M in the lower portion of hopper D to prevent clogging, and that the substance to be sifted may be equally distributed into sieve B. Motion is imparted to sieve B by revolving-wheel C. i

Having thusfully described my invention, what I claim asnew, and desire to secure by Letters Patent, is`

The combination of wire E E, pivot N, aperture H, od I|,'rod I, and hooks O, as described and for the purpose-s peciiied. i l
